MOUNTING FOB VIBBATORY ELEHENTS OI GLIPPEBS.

Application men August a, 1924. Serial No. 731,197.

- My invention relates to cli pers and more particularly to vibratory c ippers and to means for mounting the vibratory elements thereof. a

B It is a purpose of my invention to provide means for mounting a vibratory element of a clipper having a movable'bla e and a sta:

'tionary blade so that the movable blade may be adjusted relative to the stationary blade to vary thetension between the blades without affecting the tuning of the vibratory member or the adjustment thereof in any other res t.

In devlcesj of this character, the vibratory element usually comprises a member of re silient material that is clamped or fixed in.

position on the casing of the device at or near one end thereof and which carries a vibratory armature at the other end thereof,

said vibratory armature carrying the movable clipper blade. I The entire device embodying the resilient member, the vibratory armature and the blade have to be moved in; order to adjust the tension between the blades and it has been found that such movement frequently throws the other. adjustments off after they have been made if this adjusting is done in the usual manner. In

the present invention, adjustment of the moving parts of the vibratory clipper is ob tained, in the direction for adjusting the tension between the blades, at a point beyond the point of securement thereof to the casing or other support for the vibratory mechanism. In this way, none of the other adjustments of the vibratory system are disturbed by adjusting the-tension between the blades and the tension is applied at a point where there is nomovement of the spring.

Other objects and advantages OfJthe invention will appear as the descri tion-of the drawings proceeds. However, desire to vhave it distinctly understood that I do not intend to limit myself to the exactdetails shown or described, but that I intend to inelude as part ofimy invention all such'obvious changes and modifications of parts as wouldfoccur to a person skilled in thisart; andvasfwould fall within the scope of the claims.

In the drawings; a Fig. 1 is a plan view of a clipper with the if cover removed showing one form of my improved mounting of the vibratory member; Fig. 2 is a fragmentary plan view of a clamping member 23. The vibratory system portion of a clipper with the cover removed showing another form of my invention; 7

Flg. 3 is a section thereof taken on the l1ne 33 of Fig. 2; and

Fig. 4 is a section taken on the line 4'4 Re erring in detail to the drawin in Flg. 1 is shown a clipper having acasmg 10 whlch is provided w1th a stationary cli per blade 11 at the forward end thereof w ich 05 is toothed as is customar and with which the movable clipper bla e 12 co-operates; The blade 12 is secured to a bracket 13 providedon the armature 14 by means of the 011F315, said armature 14 being secured at the opposite end thereof to a resilient member 16 by means of the securing means 17, s a1d securing means 17 also carrying the llghter springs 18 with which the adjusting screws 19are adapted to engage. The resillent member 16 is provided with a re-clirved portion 20 terminating in the end portion 21 which is clamped to the enlargement 22 provided on the casing 10 by means of a comprising the armature 14 the resilient member 16 and the blade 12, is vibrated by meansof an electro-magnet comprising the coil 24 having. a core 25 provided with the laterally extending portions 26 and 27 which 35 extend in close proximity to the offset end portions of the armature 14, current being supplied to said coil 24 by means of the conductors 28.

' The adjusting screws 19 are provided for adjusting the tension on the resilient members 18 whereby the period of vibration of the movin system may be adjusted. It will be noted t at the member 23 clamps the resilient member;16 along the portion 21there-e of to the enlargement or abutment 22 at some distance from the extreme end por-' tion thereof.

The enlargement or abutment 22 is provided with a cut away portion or recess'at 29 within which'is seated the head 30 of a screw 31'havin screw-threaded engagement. with a screw-t readed openin 32 in said member 22. It will be seen t at the head of the screw engages with the upper edge of the end portion 21 of the member 16, sald 30 of the screw engages. It will be obvious,

upon reference to Figs. 1 and 4, that if the screw 30 is tightened or turned downwardly, this will tend to move the blade 12 into firmer engagement with the bladell and if the same is moved upwardly, the tension between the blades 11 and 12 will be reduced. This adjustment can be made without having any eiiect on the adjustment of the screws 19 due to the fact that said adjusting screw is located between the free end of the resilient member and the point at which the same is clamped to the casing.

Instead of providing the adjusting means on a resilient or spring member that has a re-curved portion terminating in an end portion extending substantially parallel to the main body portion thereof, as shown in Fig. 1, the resilient member may be'made straight as will be clear from Figs. 2 and 3. In this figure, the resilient member to which the armature is secured is indicated by the numeral 16 and corresponds to the member 16 in Fig. 1. In this construction, the casing 10 is provided with an enlargement or abutment 22 against which the member 16 is clamped by means of the bolt-like member 23' corresponding to the member 23 in Fig. 1. It will be noted that the member 16' has an extension 34 which extends beyond the clamping means 23. The bottom 35 of the casing 10 is provided with a screw-threaded opening through which the adjusting screw 36 extends which engages with the extension 34 of the member 16 and it will be obvious that if said screw 36 is turned upwardly or into the casing, the resilient mem er 16 and the armature and blade carried thereby will be tilted downwardly so as to increase the tension between the movable and stationary blades of the same whereas if the screw 36 is turned downwardly or out of the casing, such tension is reduced. It will also be noted that due to the fact that the resilient member 16 is clamped to the casing by means of the member 23 at a point spaced from the end thereof and that said-member is engaged by the means for adjusting the tension between the' blades between the end thereof and said clamping means, the adjustment of the tension between the blades will not affect the adjustment of the tension on the resilient member carrying the armature.
